Measuring device used in mining and tunnel construction for detecting oil-like substances in water-oil emulsions, comprises a probe having an intensive light source and a photoresist

摘要

Measuring device for detecting oil-like substances in water-oil emulsions comprises a probe (2) having an intensive light source (8) and a photoresist (9) that is sufficiently sensitive for the radiation arranged in a liquid-tight capsule (5) which has partial regions of electrically conducting material. At least one partial region, the light source and the photoresist are connected via lines (10-14) in a cable (3) to an electronic supply and evaluation unit which produces optical and/or acoustic signals.
